You know those programs for blocking out pornography, like Xstop? Well I wouldn't be surprised if Watchtower starts sending a special apostate-website-blocking program to all publishers to install on their computers and other internet-enabled devices. I believe that this is a very real possibility.
And to ensure compliance, they might make it so that when you install you must register your name and congregation and that information is sent to Watchtower VIA your internet connection. And if/when you uninstall a notification of this is also sent to Watchtower. That way the elders in each congregation can keep tabs on who in the congregation haven't installed the software so that they can provide them with "loving assistance" to make full use of this "loving provision" from Jehovah to safeguard their spirituality.
